I don't think an unwanted child is going to be happier, nor a child whose parents would rather not be together and blame the child. Of course there are those who think it is better to be tortured then not.
Too many marriages happen due to mistakes, often pregnancy and that is what leads to a bad marriage and often divorce.
As for women currently getting subjugated, consider all the laws on stopping a women from evicting an unwanted guest. A man can shoot a trespassing child and claim standing his ground, a bit of a hassle until he is exonerated as the law says you can stand your ground. Never are men punished for causing the need for an abortion, while women are subjugated to punishment, even in cases of rape in some States, and usually it is man that initiates the whole thing leading to the unwelcome guest who needs evicting with the argument that eventually it will be a person with a soul.
